You snooze, you lose. JetBlue's all-you-can-fly pass had its share of haters who questioned its value, but there were more than enough enthusiasts that were gung-ho for the deal. The special passes sold out before the promotion was scheduled to expire, and a JetBlue spokeswoman said, "We wanted to ensure those who bought the pass could get the flights they want, so we capped the number of passes we would sell."
I imagine the passes were popular with business travelers, workers with banked vacation time, and couples in long-distance relationships, and apparently the special brought out some interesting folks who just love to spend time in airports. Time tracked down aerophile and freelance IT consultant Seth Miller who plans to board 10 flights in 60 hours without ever leaving the airport. While JetBlue isn't profiting from people like Miller, overall it expects the promotion will "generate a fair amount of revenue."
